Preoperative Axillary Ultrasound versus Sentinel Lymph Node Biopsy in Patients with Early Breast Cancer.

Preoperative Axillary Ultrasound versus Sentinel Lymph Node Biopsy in Patients with Early Breast Cancer. Medicina (Kaunas). 2020 Mar 13;56(3): Authors: Rukanskienė D, Veikutis V, Jonaitienė E, Basevičiūtė M, Kunigiškis D, Paukštaitienė R, Čepulienė D, Poškienė L, Boguševičius A Abstract Background and objectives: With improved diagnostic means of early breast cancer, the percentage of cases with metastasis in axillary lymph nodes has decreased from 50%-75% to 15%-30%. Lymphadenectomy and sentinel lymph node biopsy are not treatment procedures, as they aim at axillary nodal staging in breast cancer. Being surgical interventions, they can lead to various complications. Therefore, recently much attention has been paid to the identification of non-invasive methods for axillary nodal staging. In many countries, ultrasound is a first-line method to evaluate axillary lymph node status. The aim of this study was to evaluate the prognostic value of ultrasound in detecting intact axillary lymph nodes and to assess the accuracy of ultrasound in detecting a heavy nodal disease burden. The additional objective was to evaluate patients' and tumor characteristics leading to false-negative results. Materials and Methods: A total of 227 women with newly diagnosed pT1 breast cancer were included to this prospective study conducted at the Breast Surgery Unit, Clinic of Surgery, Hospital of Lithuanian University of Health Sciences Kauno...

Conclusions: Our report is the first study to examine the distant metastatic breast cancer proteome using FFPE tissues. The depth of our dataset allowed us to discover a novel biomarker candidate and a proteomic characteristics of distant metastatic breast cancer. Distinct molecular features of various breast cancer subtypes were also established. Our proteomic data constitute a valuable resource for research on distant metastatic breast cancer.

In conclusion, we designed specific and sensitive methods to detect LALBA transcripts. We show for the first time a differential expression of these transcripts, but we need to confirm their potential use as markers in breast cancer. PMID: 32464003 [PubMed - indexed for MEDLINE]

However, and despite evidences of the existence of RANK-positive hormone receptor (HR)-positive breast tumors, the implication of RANK expression in HR-positive breast cancers has not been addressed before. Here, we report that RANK pathway affects the expression of cel...

HER2 is a transmembrane tyrosine kinase receptor, belonging to the epidermal growth factor receptor (EGFR) family, which is overexpressed in less than 20% of breast cancers [1]; as early as 1986, HER2 was established as a strong negative prognostic marker [2]. The monoclonal antibody trastuzumab was the first targeted agent specifically designed for the treatment of HER2-positive BC. Trastuzumab is directed against the extracellular domain of HER2 leading to the inhibition of the receptor, and blockade of the autophosphorylation cascade, and cell degradation via immunological effects.
